Abstract: Light is projected through a grid (e.g., a Ronchi ruling) and onto a background, where it forms an image of the ruling. The light from this projected image is then reflected back onto the same grid, with a polarizing refractor (e.g., a Rochon polarizing prism) imparting a small offset between the projected and reflected light, and then on to an imaging camera. Thus, a separate source and cutoff grid is not needed, resulting in a focusing schlieren system that is compact and easy to construct and align. In some embodiments, translation of the polarizing refractor along the instrument axis provides a sensitivity adjustment of the resulting schlieren images. Manipulation of the polarization state of the light through the system allows the projected and reflected light to be coincident, maintaining a small footprint for the system, which can be mounted to the front of the imaging camera.
